Electric vs Magnetic Fields: Key Differences Explained
Electric fields are invisible forces created by any electric charge; magnetic fields are the push generated by moving charges or permanent magnets.
People swap the two because both are silent, invisible, and measured in similar units—yet one powers your phone while the other sticks magnets to your fridge. That overlap tricks memory.
Key Differences
Electric fields radiate from static or moving charges, measured in volts per metre. Magnetic fields only appear when charges move, measured in teslas or gauss, curling around the current direction.
Examples and Daily Life
Lightning shows raw electric fields; MRI coils use intense magnetic fields. Chargers rely on electric fields, while fridge magnets illustrate stationary magnetic ones.
Can you shield a magnetic field like an electric one?
No; electric fields stop at a metal cage, but magnetic fields need thick iron or mu-metal to redirect, not block.
Which field is stronger near a power line?
Close in, the electric field dominates; step back and the magnetic field from the current becomes more noticeable.
